Mini Challenge Results

Have your knees bent and the balls of your feet and heels placed flat on the ground. Place your hands on opposing shoulders, so that your arms are crossed over your chest, or behind your head. Keeping your heels on the ground and your toes flat to the ground, slowly and gently lift your head first, followed by your shoulder blades. Hold the position for a second.

Place your toes and hands on the floor, making sure your back and arms are straight. Keep your hands slightly more than shoulder-width apart and tighten your abdominal muscles. Inhale as you lower yourself to the floor, stopping as your elbows reach a 90-degree bend. Keep your body from touching the floor. Exhale and push yourself away from the floor. Don't lock your elbows, and don't bend your back.
A modified pushup:
Place your hands and knees on the floor. Keeping your gluts and abs tight, your back should be in one diagonal line with your head and neck, and your feet should be lifted from the floor.
